[Public-List] no power to propeller

[Bradford Cooke]

Hi Guys,
Thank you for your replies.  The prop has been cleared at all times, so I
don't think that something wrapped around the prop is the problem. The
onset was more gradual.  I have a Gray Marine manual, and there is an
option for a hydraulic clutch described in it. I'll have to check and see
what my engine has on it.

Thanks, Don for your thoughts about the drive shaft nut and the keyway.

Hope all of you are enjoying the season so far,
Brad Cooke
